division of whole numbers
the meaning of division of whole numbers with and without remainders;
relate division to fractions and to repeated subtraction.
Subtraction into Division
City Blocks for Understanding Remainders
division of whole numbers with remainders to the form a=bq+r, e.g.
34 ÷ 5 = 6 r4, so 5 x 6 + 4 = 34; note remainder (4) is less
than divisor (5).
mathematical statements involving division for given situations.
and divide whole numbers
a multi-digit number by a two-digit number; recognize and be able
to explain common computational errors such as not accounting
for place value.

meaning of decimal fractions and percentages
the relative magnitude of ones, tenths, and hundredths and the
relationship of each place value to the place to its right, e.g.,
one is 10 tenths, one tenth is 10 hundredths.

fractions as division statements; Find equivalent fractions
a fraction as a statement of division, e.g., 2 ÷ 3 = 2/3, using
simple fractions and pictures to represent.
two fractions, e.g., 1/2 and 1/4, express them as fractions with
a common denominator, but not necessarily a least common
denominator, e.g., 1/2 = 4/8 and 3/4=6/8; use common denominators
less than 12 or factors of 100.
and divide fractions
the product of two unit fractions with small denominators using an
a fraction by a whole number and a whole number by a fraction, using
simple unit fractions.
Fractions by Integers
and subtract fractions using common denominators
and subtract fractions with unlike denominators through 12 and/or
100, using the common denominator that is the product of the denominators
of the 2 fractions, e.g., 3/8 + 7/10: use 80 as the common denominator.
